Obama Aides Weigh Bid to Tie the G.O.P. to the Tea Party

WASHINGTON — President Obama’s political advisers, looking for ways to help Democrats and alter the course of the midterm elections in the final weeks, are considering a range of ideas, including national advertisements, to cast the Republican Party as all but taken over by Tea Party extremists, people involved in the discussion said.

White House and Congressional Democratic strategists are trying to energize dispirited Democratic voters over the coming six weeks, in hopes of limiting the party’s losses and keeping control of the House and Senate. The strategists see openings to exploit after a string of Tea Party successes split Republicans in a number of states, culminating last week with developments that scrambled Senate races in Delaware and Alaska.

“We need to get out the message that it’s now really dangerous to re-empower the Republican Party,” said one Democratic strategist who has spoken with White House advisers but requested anonymity to discuss private strategy talks.

Democrats are divided. The party’s House and Senate campaign committees are resistant, not wanting to do anything that smacks of nationalizing the midterm elections when high unemployment and the drop in Mr. Obama’s popularity have made the climate so hostile to Democrats. Endangered Congressional candidates want any available money to go to their localized campaigns.
